BALL-BEARING.

T0 all who/n z't 'may conccrn:

Be it known that I, LICK L. CARTER. a subject of the King of Great Britain, residing' at Coudersport, county of Potter, State of Pennslvlvania, have inv'ented certain new and useful Improvements in Ball-Bearings, of which the following is a specification.

This invention relates to improvements in ball bearings, and more particularly to improvements in thrust bcarings.

The object. of the invention is to provide an improved ball retaincr and Separator.

I accomplish the objects of niy invention 1y the devices and means described in the following specification. The invcntion is clearly defined and pointed out in the claims.

A structure which is a preferred embodi- I ment of my invention is illustrated in theaccompanying drawing forming a part of this specification, in which:

Figure I is a plan view of the base retainer and Separator.

Fig. II is an enlarged detail cross section on line 2-2 of Fig. I, showing the relation of one ball to the retainer and ball races.

Fig. III is an enlarged cross section on line 3-3 of Fig. I.

In the drawing similar numerals refer to similar'parts throughout the several views, and the sectional views are taken looking in the direction of the arrows at the ends of the section lines.

In the drawing, 1 and 2 are merelv conventional showings of the relatively rotating bearing members having races therein for the reception of bearing balls 3 which are retained in separators formed from twoannnlar plates 4 and 5, respectivel-v, which are slightly dished or convexed so that when their outer edges are placed together, their inner edges will .be slightly spaced apart, as indicated at 6. The outer edges of the annular members 4 and 5 are cupped and seamed together, as shown at 7.

The opposed annular plates are perforated and flanged at regularly spaced int-ervals to form the ball receiving pockets or sockets 9.-

specification of Letters'atent.

' lubricant.

' Patented Got. 9, 1917.

Application filed February 10, 1917. Serial No. 147,765.

-dicated .at (i. an annular passage way is formed within the ball retainer, which assists the ci'rculation and 'distribution of the Due to the faotthat 'lubricant centrifugally fiows outward while the retainer is rotating andvisonly able to circulate through the ball pockets as the retainer is sealed on its periphery, a continuous washing out, cooling and lubricating of the balls results.

Having' thus desoribed my invention, What I claim as new and desire to secure by Letters Patent is:

1. In a thrust bearing, the combination of bearing members, bearing balls, a'ball retainer for saidballs comprising opposed an- 'nular dished/ plates having their peripheries cupped and 'seamed together and their inner edges spaced apart, the opposed plates being perforated and fianged to Vform retaining pockets forsaid'balls and for circulation of lubricant.

In a thrust bearing, the combination of bearin: members. bearing balls, a ball retainer for said balls comprising opposed annular dished plates having their peripheries in contact and their inner edges spaced apart, the opposed plates being perforated and fianged to form retaining pockets for said balls and for circulation of lubricant.

3. In a. thrust bearing. the combination of bearing members, bearing balls, a ball retainer for said balls col'nprising opposed annular dished plates having their peripheries in contact and their inner edges spaced apart, the opposed plates being conformed to retain 'said balls and for circ-ulation of lubricant.

4. In a thrust bearing, the combination of bearing members. bearing balls, a ball 'retainer for said balls comprising opposed annular dished plates having their peripheries in contact and ltheir inner edges ;spaced apart, the opposed plates being conformed to retain said balls. v

In witness whereof, I have hereunto set mv hand and seal in the presence of two witncsses.
